In fact, he pressed 'record' during the practice and the take was perfect so it ended up on the album.

The guitar solo was recored in one take by Thobbe Englund, who was tricked by the producer Peter Tägtgren, who said that he's going to the bathroom and they will record when he gets back, so in the meantime Thobbe can practice the solo.

It was inspired by Accept's song 'Metal Heart' that used Beethoven's 'Für Elise' as the guitar solo.

The guitar solo in the song is Bach's 'Air on the G String'.Also, in German instead of 'Not a battle' which the band used, 'No battle' ('Keine Schlacht') would be the correct form. It should be ' Keine Schlacht, eine Rettungsaktion' since both Schlacht and Rettungsaktion are of female genus in German. The song topic comes from the book 'Endgame' by David Strafford which Joakim got from a fan.

The band was asked to make theme song for the Hearts of Iron game, but some time later they came across the story of Walter Wenck and it took a while to actually compose the right song for the topic.The song title was inspired by a video game series 'Hearts of Iron'.
